'DISTILLING APPARATUS FOR CABBONACEOUS FUEL.

.Application 111m October 14, 1am. semi No. 594,642.

The invention relates to improvements in a gas making and storing apparatus particularly adapted for small consumers and for domestic uses in localities where municipal gas is not available.

It is an object of-the invention tov provide a gas making apparatus having a generator ada ted to receive av charge of carbonaceous fue with means contained in said generator for vaporizing the volatile constituents of said charge, which volatile gases are store for consumption as needed.

In a more specific aspect, the invention contemplates the provision of a gas generating outfit, which may be readily installed in any home or locality and whichis so con structed that it ma e transported with ease for installation. e casing of the generator receives a charge of comminuted carbonaceous fuel, preferably mixed with oil and of a lastic consistency, having extending theret rough a pluralltyof corded 0 en-,

ings. The generator is provided wit ,a heater capab e of developing suflicient heat to vaporize the volatile constituents in the fuel mamwhich vapors and gases pass on througha scrubber and then into a storage receiver, from where they are consumed as desirable. Only a comparatively small guantity ofheat-is needed in the generator to evelop a large "uantity, of gas, it being un* derstood that a ter a charge of the comminuted fuel is introduced to the chamber, the same ma be continuously heated until the entirevo atile content has been gasified or gases may be intermittently produced from the charge by the control of the heater.-

In the accompanying drawings: Fig. 1 is an elevationgpa-rtly' in vertical section .of the generator; i v.

Fig. 2 is a plan view; and F ig.-3 is an elevation of scrubber and receiver.

Referring now more pa'rticularl to the drawings, wherein like reference '0 aracters' indicate correspondingparts, the numeral 1 designates the body of the; gas generator,

the generator,

which ispreferably of a composite structure,

having an inner metallicwall 25fwith inner and outer layers of insulating material surrounding sa'id wall. The body is disclosed as being of a tubular form, although it will beappreciated that the confi ration thereof. may vary in any manner ound to be dethereto by complemental threads:

packing 11' to pintl'e members 2 and 3 constitute pivots for the fastening bails 5 and 6 to which they are attached.

Disposed within the generator body 1 there is an electric grid 7 formed of any suitable material and insulated from said body. Said grid is shown as extending across the body at the lower end thereof, but its configuration may, of course, vary. The grid is preferably formed with a plurality of upstanding resistance elements 8 for the purpose of applying heat directly to the Walls of the apertures formed in the fuel mass to be later described, causing a re id penetration of said mass and vaporization of the volatiles therein. The grid is connected to an electrical conductor 9, which conductor is controlled by the electric switch in a housing 9' 7 extending to one side of the generator. The

generator body 1 is seated on a separable base 10, having projecting downwardly therefrom the supporting'leg's 11.- The up per ends of the legs enter sockets in the side of-the base 10, being preferably connected The lower portions of the legs enga e and carry the supporting feet 14. The use has an upper annular socket therein receivin the rovide a firm and noncaking connection erator and the base. Along its periphery the etween the side of the genbase is also formed with a. series of slots 15. I

receiving the hinge bails 6Jcarrying,the adjustable nuts 16, by means of which the body is firmly united to the base. The lower portion of the base preferably hastlie cavity 17 therein to receive theinsulating material 29 for the grid. The generator isalso provided with a removable closure 18, preferabl" of metal or thelike, having an annular soc et' in its under surface receiving a packing 13), which engages the upper edges of the, wall of the generator maintainedina sealed position by means of closurein position. The closure is formed with a central gas outlet 23, to which there The closure is is connected a tube 24, said tube leading to a manufacture of as, and is produced in the' manner disclose in my Patent No. 1,420,- 163, dated June 20, 1922. This fuel mass rapidly yields its volatiles when the switch 9 is turned on and the grid 7 heated. The heat generated by this grid, or an equivalent heater, passes into the passageways 24' and rapidly attacks the walls thereof, va orizing the volatile content of the mass. hese volatile gases are produced in substantial.

quantities by the use of little heat by the grid 7 and constitute a gas of a very'higlh heating value. They discharge through t e pipe 24 into the scrubber 26 and then pass into the receiver where they are collected for subsequent use. When a fuel charge has been largely robbed of its volatile content,

a coke residue is formed in the generator,

which is then removed from the generator and a new mass of green fuel substituted in its place. The coke removed can be employed for use wherever a fuel of this charactor is desired.

Having thus described my invention, what I claim s:

1. In a batch distilling apparatus for generating gas and prodiicing coke, a heat insulated gas generating chamber adapted to receive a'charge of solid carbonaceous fuel, a removable base for said chamber, a removable closure for said chamber, an electric grid seated on said baseand insulated therefrom having upstanding heating elements projecting upwards therefrom into said chamber, for removing volatiles from the fuel and producing a residue of coke, means for conveying gases from said chamber and means for permitting the removal of the coke.

2. In a'batch distilling apparatus for generating gas and producing coke, a gas generating chamber adapted to receive a charge of solid carbonaceous fuel and havingabase, an electric grid seated on the base thereof having upstanding heating elements projccting upwards therefrom into said chamber for removing volatiles from the fuel and producing a residue of coke, means for permitting the removal "otthe coke from the chamber, and'means for conveymg gases from said chamber. 4 I v 3. In a batch distilling apparatus for generating gas and producing coke, a heat insulated gas generating chamber, a removable base for said chamber, a removable closurefor said chamber, an electric rid seat ed on. said base and insulated t erefroin, said grid being adapted to support a Mr guette of carbonaceous material having ormed passageways therein extending 'therethrongh to receive said upstanding elements projecting fromsaid grid, and-means for conveying gases from said chamber.

4. In a batch distilling apparatus for generating gas and producing coke, a gas gen- 'erating chamber, an electric grid seated on the base thereof having upstanding heating elements projecting upwards therefrom, said grid bein adapted to support a briquette of carbonaceous material, having formed passageways extending therethrough to receive sai upstanding elements projecting from said grid to remove volatiles from the fuel charge and producing a residue of coke, means permitting the removal of coke from the generating chamber, and means for conve ing gases from said chamber.

' 5. n a batch distilling apparatus for generating gas and producing coke, a heat insulated' gas generatin chamber adapted to receive a charge of so id carbonaceous fuel, said chamber'having a base, a removable closure for said chamber, an electric grid seated on said base and insulated therefrom serving to remove volatiles from" the fuel charge and produce a residue of coke, means permitting the removal of the coke froi n the apparatus, and means for conveying gases from said chamber.

In testimony whereof I afiix my signature.
